TVS - Varistors, MOVs are electronic components that combine the features of both resistors and capacitors. As such, they are used to protect sensitive circuits from transient voltage spikes, which can damage or destroy vulnerable components. The B72210S0200K101 is an example of a TVS - Varistor, MOV designed for reverse-voltage protection.

The B72210S0200K101 is a radial-lead, bidirectional Varistor with a nominal capacitance of 0.2uF, a working voltage of 200V, and a maximum clamping voltage of 270V. It is designed to provide both over-voltage and under-voltage protection to a variety of electronic circuits and components.

Application Field

The B72210S0200K101 Varistor is designed for use in applications where moderate levels of reverse-voltage protection and noise filtering are required. It is most commonly used in industrial, automotive, and consumer electronics applications, as well as in telecommunications, automotive, and medical equipment. Examples of these applications include:

• Industrial Control and Automation Circuits
• Power Supplies and Adapters
• Communications and Network Equipment
• Automotive Electronics
• Consumer Electronics, such as Audio/Video Devices and Television sets
• Medical Equipment such as Patient Monitors and Anesthesia Machines

Working Principle

The working principle of the B72210S0200K101 is based on the fact that the varistor is a nonlinear device, meaning that the capacitance between its leads changes with the applied voltage. When there is no voltage between the leads, the varistor is said to be in its “open state”, in which its capacitance is low. As voltage is applied to the leads, the capacitance between the leads increases, and the varistor is said to be in its “closed state”, in which its capacitance is high.

When a transient voltage spike occurs, the varistor’s capacitance instantly changes, which causes the varistor to absorb most of the energy from the voltage spike. The energy absorbed by the varistor dissipates into heat and dissipates quickly, thus protecting the components of the electronic circuit from the effects of the spike.

The B72210S0200K101 is designed to provide both over-voltage and under-voltage protection, making it a versatile component for both consumer and industrial applications. It is also designed to be able to handle high transient-voltage spikes, making it an ideal choice for high-voltage applications.
